为了充分利用含砷铁矿资源，在实验室条件下，采用Si-Ca-Ba合金＋CaF2对钢液进行了脱砷研究。分析了Si-Ca-Ba合金比例、试验温度、脱砷剂加入量以及初始硫质量分数对脱砷反应的影响。研究表明，Si-Ca-Ba合金比例在65%～75%范围内脱砷效果最明显。在相同试验操作条件下，提高钢液温度、增加脱砷剂加入量和降低钢液中初始硫质量分数可以增大脱砷率。
To make full use of domestic iron ore containing arsenic,the dearsenication agent of Si-Ca-Ba alloy+CaF2 were researched in laboratory. It has been shown that the ratio of Si-Ca-Ba alloy,temperature,the amount of dearsenica-tior and initial sulfur content in molten steel can affect the results of dearsenication. The present results indicate that the ra-tio of Si-Ca-Ba alloy which is in the range of 65%-75%has the most obvious dearsenication effect. Simultaneously,ele-vating temperature of molten steel,increasing the amount of dearsenication agent and reducing the initial sulfur content can improve the rate of dearsenication..
